Step By Step Configuring Oracle 10gR2 (10.2.0.5) 3-Nodes RAC to Single Dataguard
Operating System:Oracle Linux 5.7 x86_64
Oracle version:10.2.0.5
RAC Primary database
192.168.1.51 racnode1
192.168.1.151 racnode1-vip
172.168.1.51 racnode1-priv
192.168.1.52 racnode2
192.168.1.152 racnode2-vip
172.168.1.52 racnode2-priv
192.168.1.53 racnode3
192.168.1.153 racnode3-vip
172.168.1.53 racnode3-priv
Single Standby database
192.168.1.59 standby
主库是一台3nodes的10g RAC,备库准备使用单实例数据库存储使用ASM
需要在standby机器上安装oracle database software并升级至10.2.0.5,安装过程略

在standby 服务器创建用户用户组
groupadd -g 501 oinstall
groupadd -g 502 dba
groupadd -g 503 oper
useradd -m -u 501 -g oinstall -G dba,oper -d /home/oracle -s /bin/bash -c "Oracle Software Owner" oracle
mkdir -p /u01/app/oracle
chown -R oracle:oinstall /u01/app
chmod -R 775 /u01/app
配置oracle用户环境变量

看意思是指log_archive_config参数不对,我检查了主备库的这个参数,发现是没有问题的
我记得在配置single dataguard的时候db_unique_name默认等于db_name,故这里没有在主库配置db_unique_name这个参数。问题就是出在这里
在主库配置db_unique_name参数重启RAC实例

还需配置standby_file_management,db_file_name_convert,log_file_name_convert这三个参数,谁能告诉我为什么后面两个参数不给修改?
只好生成pfile,通过修改pfile启动实例重新生成spfile
SQL> alter system set standby_file_management='AUTO' sid='*';
System altered.
SQL> alter system set db_file_name_convert='+DATADG/standby/','+DATADG/racdb/' sid='*' scope=spfile;
alter system set db_file_name_convert='+DATADG/standby/','+DATADG/racdb/' sid='*' scope=spfile
*
ERROR at line 1:
ORA-02096: specified initialization parameter is not modifiable with this option
SQL> alter system set log_file_name_convert='+DATADG/standby/','+DATADG/racdb/','+DATADG/standby/','+FLASHDG/racdb/' sid='*' scope=spfile;
alter system set log_file_name_convert='+DATADG/standby/','+DATADG/racdb/','+DATADG/standby/','+FLASHDG/racdb/' sid='*' scope=spfile
*
ERROR at line 1:
ORA-02095: specified initialization parameter cannot be modified
修改pfile后使用以下命令创建spfile,然后重启rac实例
create spfile='+DATADG/racdb/spfileracdb.ora' from pfile='/tmp/rac1.ora';
srvctl stop/start database -d racdb
